Planting A Strawberry Tree In A Pot

Last month, my brother-in-law visited us. He came from Pemalang, Central Java. Some of the Pemalang district is a mountainous area. The weather is cold and it is good to grow strawberries. He has some strawberry trees in pots. He brought a pot to us.

In one pot, there are a lot of trees. Planting a strawberry tree is not difficult. We can cut one young shoot and plant it in another pot. The shoot will grow and spread with the new shoots.
This afternoon, I took a shoot from the main pot.
I put the shoot in a new pot. I gave the strawberry tree to my neighbor. He likes to plant flowers and trees in his yard. The temperature in Bekasi is not too cold, but I hope the strawberry tree will be able to bear fruits in the future.
I also tried to spread other shoots into some poly-bags. I hope I will have a lot of strawberries in the coming months.
I have no knowledge about strawberry gardening in pots, but I think I should learn about it. My brother-in-law had no knowledge of how to plant strawberry but he learned while he was planting. The result is that some of his strawberry trees in his pots bear a lot of fruit in Pemalang.
Strawberries are not from Indonesia, but some areas are suitable for cultivating them. The producers of strawberry fruits are Bogor, Bandung, Pemalang, Malang, and other cold and mountainous areas. Do you have any experience how to plant strawberries?
